To a/ZZ 1,071,011@ it may concern: 1 Be it known that I, PETER KELLER', a citizen of the United States, residing at Chicago,

in the county of Cook and State of Illinois, have invented certain new'and useful Improvements in Carbureters; and I- do hereby declare the following to be a full, clear-,fand exact description of the invention,'sfnch vas will enable others skilled in theart t'o whichit appertains to make and use the same.

My invention relates to an improved form of carburetery for producing illuminating gas by the use of a hydrocarbon liquid,.the' object being to make a' carburetor whichwill` the space 3, said space being designed to be filled withwater for cooling purposes. Said vessel 1 is divided into two main compartments 4 and 5 by the horizontal partition 6, the upper compartment 4 being a storagespace for the liquid used in the carbureter and said lower compartment 5 being designed for a mixing-chamber. The storage-chamber 4 is connected to the mixingchamber 5 by means of the dependentpipe 7,'the ii'ow of liquid through same being controlled by means of the float-valve 8, whichis designed to maintain a predeterminedlevel of the liquid in said mixing-chamber 5. The upper end of said pipe? isprotected by the wire screen 8a to preventanyy extraneous particles from finding their way into said mixing-chamber. The lower end of said pipe 7 extends to near the bottom of said chamber and ends below the surface of the liquid as maintained by the iioatvalve S. The upper portion 9 of said mixing-chamber 5 is separated from the lower portion 10 of same by the foraminated horizontal partition 11 and is designed to con- Fig. 2 is a horizontal section on tain cottonor other fibrous material for the Apurpose of preventing any liquid particles of the liquid from being carried out of the carbureter along with .the mixed gases. The lower portion 10 ofsaid mixing-chamber 5 is connected' to the inlet-pipe A12 by the pipe 13, which enters through the'wall of the outer "vessel 22 near .its top edge, thence passes i downward in the :space 3l and enters said chamberlO *a little above the level lof the liquid therein. mixing-chamber is connected to the deliverypipe 14 by the pipe X15, which enters said 'outer Vessel 2 on a level with and diametric ally opposite to said inlet-pipe 12, thence lpassesdownward through the space 3 and enters said chamber 9 near its upper wall. Topre'vent said cotton in chamber 9 from stopping the orifice of said pipe 15, a wire screen 16 is placed in said chamber so as to leave a clear space -in front oflsaid orifice. Said inlet`and delivery pipes 12 VVand 14 are supplied with valves 17V and 18 for controlling the tlowof gases therein. A small chamber19 is provided `in the upper portion of said storage-chamber i4, adapted to contain the filling-tube 20 and Vent-tube 21, each of.

which is provided with a stop-cock 22 and 23 and screw-cap 24 and 25;` respectively. Said vent-tube 21 is connected by means of the pipe 26 tothe deliyery-pipe15, forming a by pass for the purpose @of equalizing the pressure in the two chambers 4 and 5.

In operating my/carbl'ureter air or other gases are forced through the inlet-pipe to the lmixing-chamber, where it will take up the vapors of the hydrocarbon liquid contained therein, the thorough saturation of the gases being helped by the absorbent wicks 27, which dependl from the foraminated partition 1 1, thelower ends of which vhang in the liquid' in said chamber 5. ,I As the liquid yin said chamber 5 is absorbedfand carried away said iioat-valve 8 operates toallow more liquid to Iiow from said storage-chamber 4 totake its place. The gases afterbeing thoroughly satue rated with the vapor of the hydrocarbon liquid in said chamber 5 pass upward through said foraminated partition 11 and thence through the cotton contained in said chamber 9 and out through said delivery-pipe 14.

The upper portion 9 of said Y IOO 'Y I am enabled to produce a very steady flow of evenly-mixed gases by means of this form of carbureter.

I claim as my invention- A oarburetercomprisingacylinder divided into three chambers by means of horizontal partitions, one of which is solid and one foraminated, the upper and lower-most chambers being adapted to contain naphtha and communicating with each other through a vertical pipe extending from the bottom of the upper chamber to a point adjacent the bottom of the lowermost chamber, a valve in said pipe controlled by a float for maintaixr ing a given level in said lowermost chamber, a filter at the upper end of said pipe, iiltering material filling the intermediate chamber and resting upon said foraminated parti-
